Solve for the ? angle

daser333 [38]

Answer:

Step-by-step explanation:

since all angles add up to 180

and since this is a right triangle the square in the corner is 90 degrees

so 40+90+x=180

130+x=180

subtract 130 from both sides

130-130+x=180-130

x=50

Hope that helps :)

-5+7q+ -5q+ -9q please help

vekshin1

For this case we must simplify the following expression

$-5 + 7q + (- 5q) + (- 9q)$

We know that, by definition:

$+ * - = -$

So, rewriting the expression we have:

$-5 + 7q-5q-9q =$

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major's sign is placed:

$-5 + 2q-9q =\\-5-7q$

Answer:

$-5-7q$
